General purpose engine

A general purpose engine which comprises:

• a crankcase configured to support an engine rotary shaft rotatably;
• a cylinder unit extending from the crankcase in a direction perpendicular to an axis of the engine rotary shaft;
• a cooling fan fixed to one of opposite ends of the engine rotary shaft on one side thereof;
• and
• a fan housing configured to have an air induction opening defined therein for the cooling fan and also to cover the crankcase and the cylinder unit from one side of the engine rotary shaft, wherein
• a cleaning access window is defined at a position of the fan housing, which position is opposed to a cooling fin of the cylinder unit,
• the cleaning access window is covered by a debris covering capable of being selectively opened and closed,
• the debris covering has one end portion engaged with the fan housing and also has an other end portion removably mounted on the fan housing by means of a magnetic body,
• the debris covering comprises:
• a covering portion opposed to the cleaning access window;
• a to-be-engaged portion engaged to the fan housing;
• and
• a retainer portion configured to retain the magnetic body,
• the retainer portion comprises a holding wall configured to hold the magnetic body in a condition with a magnetic attracting portion exposed to the fan housing,
• the holding wall includes:
• a pair of longitudinal walls, which extend downwardly from an inner surface of the debris covering;
• and a bottom wall connecting the pair of longitudinal walls together,
• the pair of the longitudinal walls and the bottom wall cooperate together to form a cross-sectional shape representing a U-shaped configuration, and the holding walls of the U-shaped configuration and the inner surface of the debris covering cooperate to define a storage space for accommodating therein the magnetic body,
• the holding wall has a slit defined in the bottom wall thereof, the slit being so as to extend completely through the bottom wall, and
• a portion of the magnetic body is exposed outwardly from the slit, the portion of the magnetic body being a part of the magnetic attracting portion.
